Reusing and treating wastewater is crucial to solving the world's water shortage issue. Furthermore, to lessen treated wastewater's detrimental effects on natural water resources and, by extension, human health, its quality must be improved. Separate applications of electrocoagulation and adsorption have proven successful in treating various wastewater. Every approach has particular advantages, disadvantages, and factors that influence how effective a treatment is. To give an overview of both processes capabilities, a study of their theoretical underpinnings, the impact of operating circumstances, and real-world applications is provided. The benefits of each method can be increased while reducing their drawbacks by combining electrocoagulation and adsorption into a single procedure. The EPA states that the finished treated water's quality met requirements for reuse.
